I had the same issue last night, Tiny! Only one let down and about half the output I normally have. The only think I could think of was maybe DD ate better than she normally does and maybe I didn't drink as much water as I normally do yesterday?
And holy moly, 40 oz?! That's insane! I wish DD would eat more... She only gained 2.5 oz this week, but she has been sick. I had an appointment with a GI doctor two weeks ago due to the reflux issues she was having and not responding all that well to Zantac. I ended up trying a homeopathic remedy before moving on to stronger meds and they seem to have worked! But they weren't too excited about her slow weight gain the previous several weeks, so they had us start fortifying her bottles during the day (both breastmilk and formula) to bring her weight up. She gained 8 oz the first week, but then this week only 2.5. She's alert and has good fat stores and is perfectly healthy, the GI doctor even said he's not concerned about her nutrition at all, just would prefer to see a 3 month old gain more weight.
Beemeck, that's always one of my fears, too! It's happened to me before so I dread it happening again. But last night DD woke up as I was going back to bed after pumping and she had plenty to eat and get back to sleep. I was so relieved! Granted, this was at 3 am and my alarm goes off at 4:30, so I never got to go back to bed...
Running on 4 hours of sleep here! I can laugh about it now.
I've also noticed sometimes DD just doesn't want a bottle and wants the boob. I wonder if that's why sometimes she only takes 1 oz with the sitter. She just eats what she must to not be starving until she can nurse. More than once I've picked her up from the sitter's and she had taken part of a bottle, then I tried to let her finish it when we got home and she refused, but latched right on when I offered the boob. She even does this with breastmilk in a bottle. I'm secretly glad she prefers me! When she first started taking formula because I just wasn't producing enough and she would get frustrated so quickly at the breast, I was so heartbroken and started to hate the bottles.
Like I was mad at them because they could give her what I couldn't.
I've never seen blood in DD's stool thankfully! How scary that would be. You both said you saw your blood in your babies' poop... I'm just curious, were your nipples bleeding? What caused your blood to be in their poop?
